SINAMICS S120 Installation and Start-Up Manual, 12/04 Edition
Particularly suitable for multi-axis applications
Coordinated drives that carry out drive tasks together are used in many mechani-
cal and plant engineering applications, including running gears in gantry cranes,
stretching systems in the textile industry, or paper machines and rolling mills.
Drives with coupled DC links are required for this purpose, as they support eco-
nomic energy exchange between braking and driving axes.
SINAMICS S120 boasts line supplies and inverter modules covering a wide power
range, which, having been designed for seamless integration, pave the way for
compact multi-axis drive configurations.
